C# AvalonDock-防止固定窗格停靠在文档窗格中

是否有可能防止锚点停靠到“我的文档”窗格中？我希望它们可以在屏幕上拖动和移动，但有时用户会将它们拖到文档窗格中，这会让它们看起来很糟糕。然后他们关上标签，我无法重新打开固定点

如果有帮助，我的Avalon代码如下：

        <avalonDock:DockingManager.Theme>
            <avalonDock:VS2010Theme />
        </avalonDock:DockingManager.Theme>

        <avalonDock:DockingManager.DocumentHeaderTemplate>
            <DataTemplate>
                <StackPanel Orientation="Horizontal">
                    <StackPanel Orientation="Horizontal">
                        <!-- the TextBlock named Limiter is used to limit the height of the TextBlock for the workflow name. -->
                        <TextBlock x:Name="Limiter" TextWrapping="NoWrap" Visibility="Hidden"
                                                       TextTrimming="CharacterEllipsis">
                                                L
                        </TextBlock>
                        <TextBlock Text="{Binding Path=Title}" VerticalAlignment="Center"
                                   ToolTip="{StaticResource WorkflowTabItemToolTip}"
                                   MaxHeight="{Binding ActualHeight, ElementName=Limiter}" MaxWidth="150"

                        <TextBlock Text=" *"

虽然我没有找到阻止停靠的直接方法，但我能够解决基本问题，即为工具窗口和文档窗口自定义不同的选项卡标题。“我的文档”窗口在选项卡标题中显示星号（*），以指示更改（就像VS一样），而工具窗口不应这样做

解决方案是使用

DocumentHeaderTemplateSelector

并为其提供两个不同的模板，分别用于文档和工具窗口。以下是XAML：

<xcad:DockingManager.DocumentHeaderTemplateSelector>
  <bd:DocumentHeaderTemplateSelector>
    <bd:DocumentHeaderTemplateSelector.DocumentTemplate>
      <DataTemplate>
        <StackPanel Orientation="Horizontal">
          <Image Source="Resources\AppIcon.ico" Margin="0,0,4,0" Width="16" />
          <TextBlock Text="{Binding Title}" />
          <TextBlock Text=" *" Visibility="{Binding Content.IsDirty, Converter={StaticResource BoolToVisibilityConverter}}" />
        </StackPanel>
      </DataTemplate>
    </bd:DocumentHeaderTemplateSelector.DocumentTemplate>
    <bd:DocumentHeaderTemplateSelector.ToolWindowTemplate>
      <DataTemplate>
        <StackPanel Orientation="Horizontal">
          <TextBlock Text="{Binding Title}" />
        </StackPanel>
      </DataTemplate>
    </bd:DocumentHeaderTemplateSelector.ToolWindowTemplate>
  </bd:DocumentHeaderTemplateSelector>
</xcad:DockingManager.DocumentHeaderTemplateSelector>

现在，我的工具窗口不显示星号（*）和图标，即使它们被移动到文档窗格中

希望这对以后的人有所帮助。

您是否找到了解决此问题的方法？您是否尝试捕获当锚点移动到窗口并将属性>更改为false时的事件？

Public Class DocumentHeaderTemplateSelector
  Inherits DataTemplateSelector

  Public Property DocumentTemplate As DataTemplate
  Public Property ToolWindowTemplate As DataTemplate

  Public Overrides Function SelectTemplate(item As Object, container As System.Windows.DependencyObject) As System.Windows.DataTemplate
    Dim itemAsLayoutContent = TryCast(item, Xceed.Wpf.AvalonDock.Layout.LayoutContent)

    If TypeOf item Is Xceed.Wpf.AvalonDock.Layout.LayoutDocument AndAlso TypeOf DirectCast(item, Xceed.Wpf.AvalonDock.Layout.LayoutDocument).Content Is DocumentVM Then
      Return DocumentTemplate
    Else
      Return ToolWindowTemplate
